The Marin County district attorney on Thursday charged 21-year-old Thomas Rector and 18-year-old Peter Kurer with misdemeanor trespassing for climbing the bridge's north tower earlier this year.

The West Bend, Wisconsin, residents were charged after posting their exploits to social media sites. A five-minute clip posted online in May shows them climbing the north tower of the iconic structure. They film themselves doing flips and hanging from cables without safety gear.
